Quaternary structures of proteins include different protein and non protein moiety to work together.

Option B

<h3><u>Explanation:</u></h3>

Proteins are the polymer of amino acids which are formed after several processing. The polypeptide chains are formed when the transcripted mRNAs are translated in the Ribosomes to produce the polypeptide chains. Then they are further processed by slicings and adding and cutting of several protein parts to this main polypeptide chains and they are slightly folded by means of hydrogen bonds between the polypeptide chain atoms to give a slightly coiled structure. Now this secondary polypeptide undergoes several structural modifications by chaperon proteins which introduce different ionic, disulphide, covalent etc bondings between different parts of polypeptide chain to produce a highly coiled tertiary structure.

Now in some proteins like haemoglobin, there are the protein part i.e globin associated with haem chains, which is the Quaternary structure of proteins. It's formed when different proteins are together associated to perform a particular function.

Question 1 (1 point)
Zarrin [17]

Answer:

The correct answer is : Kinetic Energy and Thermal Energy.

Explanation:

  • Water Cycle involves the evaporation of water into water vapour, condensation of water vapour to form clouds followed by precipitation.
  • The heat energy or thermal energy from the sun increases the vibration of water molecules (kinetic energy) to an extent that the change of state, from liquid to gas occurs resulting the formation of water vapour.
  • The water vapour condenses to form clouds by releasing heat energy.
  • When the water content in the cloud become more than its holding capacity, precipitation occurs.

This crack shown in the lithosphere was created by the movement of two or more tectonic plates. What is this crack called?
pav-90 [236]

Answer:

Fault

Explanation:

A break or crack in earth's lithosphere along with rocks move. Earth is made up of 4 basic layers a crust,mantle,outer core,inner core and lithosphere.  A solid crust and hard layers of mantle  make up a region name the lithosphere. The lithosphere is made up of pieces of tectonic plates. These plates are constantly changing and move towards the mantle. Non-stop movement of tectonic plates causes stress on the earth's outermost layer i.e,the crust. When these stresses extends it leads to cause cracks called faults.
